Tofu is supposed to be the replacement for meat in our diets that saves us all from ourselves. Tell that to the 55 year old man from China who had 420 kidney stones removed from his left kidney. He ate a diet heavy in tofu and drank very little water. The result was a build up of calcium kidney stones. The stones were removed in a two-hour operation performed at a hospital in Dongyang, eastern Zhejiang Province, China.

The man is known only as Mr. He. He visited the doctor in May because of abdominal pain. A CT scan revealed the 420 kidney stones in his left kidney. Doctors said that had he not come in when he did he would have had to have the kidney removed. These 420 stones are not the world record for kidney stones. According to the Guinness Book of World Records a doctor in India removed 172155 stones from the left kidney of another patient. That surgery took three hours to complete.
